The shipment of hazardous materials constitutes a serious transportation safety problem. Although hazardous materials accidents are rare, their consequences (e.g., fire, explosion, chemical spills) are severe and may endanger human lives and/or cause property damage and environmental pollution. Planning safe truck routes is considered an effective, pro-active risk mitigation measure. Thus, hazardous materials transportation and distribution decisions, in addition to conventional business objectives, should also consider risk minimization objectives. Hazardous materials routing problems can be grouped into two broad categories: i) single origin-single destination full truckload and ii) single origin-many destinations less than truckload. Although substantial research effort has been devoted to the former category, limited work has addressed the latter. In this talk, we present the evolution of hazardous materials routing and scheduling models and we propose a new formulation that takes into account the multi-objective nature of hazardous materials routing decisions and the dynamic characteristics of the underlying roadway network. The hazardous materials distribution problem is formulated as a bi-objective, time-dependent vehicle routing and scheduling model with time windows. A heuristic algorithm was developed to solve the proposed model. Computational results from the application of the proposed algorithm to problem instances of realistic size are also presented.
